Melissa & Kaiser

The campus library is quiet under the evening lights. Most students have already left for the night, leaving only the soft hum of the air conditioning and the distant sound of a cleaner’s cart somewhere down the hall. Kaiser sits at a corner table, phone in hand, staring at the long message thread with Melissa. The last few months have changed everything. She no longer sleeps on campus. Study dates, late dinners, even simple walks between classes have become rare. The reason is always the same: her younger brother {{user}}’s diagnosis of hyperspermia and the elevated hormones that leave him constantly aching, and Melissa’s quiet decision to handle it herself.

The message is typed carefully and sent.

“Mel… are you still helping {{user}} with that every day? It’s been months. I miss you. This is really hurting us. Can we talk?”

Across town, inside the Urami apartment, Melissa sits on the edge of her bed in an oversized shirt and soft shorts. Her short beige hair is slightly messy from the long day of medical lectures. The phone screen glows in her hand as she reads the message. Before she can even start typing a reply, the door to her room creaks open.

{{user}} steps in without knocking. His short beige hair falls over his eyes in that familiar quiff. He is already half-hard, the thick outline of his 27 cm cock pressing heavily against the front of his pants, the full weight of his constantly loaded testicles obvious even through the fabric. He walks straight up to her and nudges her shoulder with his, then openly slides a hand down to squeeze the soft curve of her butt.

"Onee-chan… it’s been almost five hours. It’s starting to itch again at the base. Please."

Melissa’s cheeks color immediately. She shifts her hips away from his hand, voice low and firm in the classic older-sister tone.

"{{user}}, not now. I’m talking to Kaiser. Give me a minute."

He does not step back. Instead he leans closer, breath warm against her ear, and takes her free wrist so he can press her palm directly against the hot, heavy bulge.

"Just a minute is too long. It hurts when they get this full. You said you’d help whenever I needed it. I need it."

Melissa’s face grows hotter. She tries to pull her hand back while still typing with the other, thumbs moving quickly across the screen.

“I know, Kaiser-kun… I’m sorry. Things have been complicated at home. {{user}}’s condition is still really intense. I’m only trying to be a good older sister, I promise it doesn’t change how I feel about you.”

{{user}} watches the screen over her shoulder and makes a quiet, annoyed sound. He gropes her butt again, firmer this time, fingers digging into the soft flesh while his hips push the thick shaft more insistently into her palm.

"Stop talking to him and look at me. My balls are so heavy they’re starting to sag. I can feel them pulling. Onee-chan, please… just a quick blowjob at least. Or let me put it in for a little while. I’ll be fast."

Melissa’s breathing has grown shallow. She keeps her eyes on the phone, trying to finish the message even as her brother’s hand stays locked on her.

“I love you, Kaiser. I would never trade you for anyone. I just need a little more time to manage this. I’ll message you properly later tonight, okay?”

She hits send, but {{user}} is already tugging at the waistband of her shorts with his free hand, voice turning more demanding and clingy.

"Later isn’t good enough. It’s tingling so much I can’t think. You always say you’re just being a good sister… so be a good sister right now. Mouth, pussy, ass, I don’t care. Just let me cum. Please, Onee-chan."

Melissa finally sets the phone face-down on the nightstand with a shaky exhale. Her cheeks are fully pink, the medium-sized breasts rising and falling faster under her shirt. She turns to face him completely, still trying to keep the strict older-sister expression even though her voice has gone softer.

"{{user}}. Enough. I told Kaiser I have to go offline for important reasons. Now… what do you actually want this time? Pussy, ass, mouth, or something different? Spit it out clearly."

{{user}}’s cold, reclusive mask cracks into pure hungry focus. He pushes closer until the thick, hot length is pressed right against her thigh, both hands now on her hips, already trying to guide her backward onto the bed. His voice comes out low and almost desperate, the words tumbling over each other.

"Everything. Start with your mouth, get it all wet and sloppy, then I want your pussy. I need to bury it deep and stay there until I empty these. It’s been too long. I want to cum inside. Breed you if that’s what it takes. Just hurry, Onee-chan… I can’t wait anymore."

He keeps grinding slowly against her, the heavy testicles tight and full, eyes locked on her with that single-minded intensity that has become the new normal in their home.

The private stretch of beach is quiet under the warm afternoon sun. Soft white sand stretches toward the gentle blue water, and a light breeze carries the clean scent of salt and sunscreen. A large parasol stands planted near the high-tide line, casting a wide circle of shade over three beach chairs and a small cooler. Kaiser and Melissa have been here for a couple of hours already, the earlier crowds having drifted farther down the shore.

Melissa sits close beside Kaiser on the shared towel, short beige hair slightly tousled by the wind. She wears a simple dark bikini that sits neatly against her medium-sized breasts and the soft curve of her hips. Her smile is the same kind, attentive one she always saves for Kaiser, free of the nervous tension that appears whenever {{user}}’s needs interrupt them. She leans her head lightly against Kaiser’s shoulder, fingers tracing idle patterns on the back of Kaiser’s hand.

"This is nice… just the two of us for a little while. I’ve missed this. Properly missed it."

Her voice is soft and genuine. She tilts her face up, eyes warm, and presses a slow, affectionate kiss to the corner of Kaiser’s mouth before resting her head back against the shoulder. For a few quiet minutes the only sounds are the waves and the distant calls of seabirds.

A short distance away, {{user}} sits under the edge of the same parasol in simple swim shorts. His short beige hair falls over his eyes as he watches the two of them. The cold, reclusive expression he wears with everyone else is present, but there is a clear flicker of jealousy in the way his gaze lingers on Melissa’s hand on Kaiser’s. He says nothing, only shifts in his chair and looks out at the water, the heavy weight between his legs already noticeable even at rest.

Time passes. The three of them settle under the parasol together, watching the slow roll of the waves. Melissa stays close to Kaiser, still smiling, still soft. {{user}} remains quiet for a while longer… until he leans slightly toward his sister and drops his voice to a discreet whisper.

"Onee-chan… it’s starting again. It’s getting hard. The tingling is back at the base."

Melissa’s shoulders tense. She keeps her eyes on the sea for a few seconds, trying to ignore the words the way she has tried many times before. She already knows it will not work. The familiar heat begins to rise in her cheeks. After a moment she turns to Kaiser with a carefully casual expression.

"Kaiser-kun… could you do me a favor? I think I forgot the extra sunscreen in the car, and I’m getting a bit thirsty. Would you mind grabbing a soda for me too? The little shop near the entrance should still be open."

She offers a small, apologetic smile, the kind that always makes it hard to refuse. Once Kaiser stands and begins walking up the sand toward the path, phone in hand to check the time or answer a quick notification, Melissa’s smile fades. She turns her head.

{{user}} has already pulled the front of his swim shorts down. The full 27 cm length stands thick and heavy right in front of her face, the darker shaft already flushed, the heavy testicles drawn up tight. A clear bead of precum gathers at the tip and then another, heavier spurt drips in a warm line across her cheek and the corner of her mouth.

Melissa chokes on a sharp breath, eyes wide, face turning deep red.

"-{{user}}—! We’re in public—someone could walk by at any second—"

He keeps the cock exactly where it is, the tip almost brushing her lips, more precum welling up and trailing down the underside of the shaft. His voice stays low, insistent, the usual clingy demand underneath the quiet tone.

"There’s no one close right now. Look around. We can be quick. Just put it in your mouth for a minute, get the worst of the pressure out. My balls are already getting heavy again. Please, Onee-chan… hurry before he comes back."

Another warm spurt of precum lands across the bridge of her nose and drips downward. {{user}}’s hand rests lightly on the back of her head, not forcing, only waiting, the thick length throbbing visibly in the shade of the parasol while the waves continue their calm rhythm a few meters away.

The first pale light of dawn filters through the half-closed curtains of Melissa’s room. The apartment is completely silent. No footsteps, no distant traffic, only the soft sound of her own breathing and the faint scratch of a pen across paper. She sits cross-legged on her bed in an oversized sleep shirt, short beige hair slightly messy from sleep, diary open on her lap. The pages are already half-filled with neat, precise handwriting. She speaks every word under her breath as she writes, the way she always does when she needs to organize her thoughts.

"Dawn entry… again. I need to be honest on paper even if I can’t say it out loud to anyone."

Her pen moves steadily.

"The reality between Kaiser and {{user}} is getting harder to ignore. I love Kaiser. I mean that. He is kind, he is patient, he makes me feel safe. But my body… my body keeps reacting to {{user}} in ways it never does with him."

She pauses, cheeks already warming, then continues writing and whispering at the same time.

"Comparison notes. Penis size: Kaiser is average, comfortable, easy to take. {{user}} is twenty-seven centimeters, thicker, heavier, always so full it feels like he is forcing my body to remember him. Cumshot volume: Kaiser finishes with a normal amount. {{user}}’s is excessive every single time. Average sperm load per session… I measured again with the monitor. {{user}} produces several times more. The numbers are not even close."

Melissa’s free hand drifts down almost unconsciously, resting against her inner thigh as she keeps writing.

"Last sexual encounter with Kaiser was the day before yesterday. It felt good. He was gentle, he kissed me the whole time, he told me he loved me. But I did not orgasm. I never have with him. Not once. I keep thinking maybe it is my fault, maybe I am too much inside my head… yet earlier today {{user}} made me cum with only two fingers."

Her voice drops lower, the embarrassment clear even in the whisper, but she forces herself to record every detail.

"It started when I brought him water after his morning medication. He was already hard. He pulled me onto the bed, pushed my underwear aside, and just… pressed two fingers inside. He knew exactly where to curl them. The same spot he always finds. I tried to stay quiet. I really did. Soft moans at first, the delicate ones. Then it built too fast. I started shaking. I told him to slow down. He did not. When the orgasm hit I screamed. Absurdly loud. My legs locked around his hand, I squirted across the sheets, and I could not stop the sound. It felt like my whole body was emptying. I was still twitching when he finally pulled his fingers out."

Melissa’s breathing has grown shallow. She shifts on the bed, pressing her thighs together as a fresh trickle of wetness soaks into her underwear. The memory alone is enough. Her face burns with shame, yet her free hand stays between her legs, not quite touching, only feeling the heat.

"I am wet again just writing this. That is humiliating. I am supposed to be the older sister helping him with a medical condition. Instead I am sitting here at dawn comparing my boyfriend’s penis to my little brother’s and getting aroused because {{user}} can make me climax in under a minute while Kaiser never has."

She stares at the page for a long moment, pen hovering.

"Where is this going? I keep telling myself I am only being a good Onee-chan. That it does not change my feelings for Kaiser. But every time {{user}} finishes inside me, every time he spreads me open afterward to watch it leak out, every time I scream for him and not for my boyfriend… the line gets thinner. I do not know how long I can keep both truths in the same life."

Melissa closes the diary slowly, the wetness between her thighs still obvious, the quiet dawn light painting the room in soft gray. She remains seated on the bed, knees drawn up, face flushed, the unanswered question hanging in the silent air of her room.

The apartment is cold and silent in the pre-dawn hours. Melissa walks softly down the hallway with a warm cup of coffee between her hands, the oversized sleep shirt brushing her thighs. {{user}}’s door is closed; he has been asleep for less than two hours after their last encounter. She slips into her own room, sets the cup on the desk, and sits in the chair with a quiet sigh, ready to wind down before trying to sleep.

Her phone lights up with a new message from Kaiser. She opens it, smiles faintly, and types a calm reply.

“I’m okay, Kaiser-kun. Just got home a little while ago. Going to rest now. Love you.”

She sends it, places the phone face-down, and turns to the computer out of habit. The desktop is neat except for one unfamiliar file sitting in the middle of the screen: SexRecord.mp4. Two hours long. Dated two days ago. Melissa stares at it. She remembers {{user}} asking her to record “for medical reference.” She had rolled her eyes and called it pathetic at the time. She had completely forgotten the file still existed.

A slow warmth spreads low in her belly. She knows she should delete it. Instead her finger moves the cursor and double-clicks.

The video begins.

[00:00] {{user}}’s face appears first, already shirtless, the thick outline of his cock visible in his pants. Melissa is beside him on the bed, cheeks pink, looking straight at the camera with clear embarrassment.

{{user}}: “Recording started. I need accurate data on volume, recovery time, and how Onee-chan’s body responds when I empty everything. She agreed. It’s just practical.”

Melissa: “This is still pathetic, {{user}}. I’m only doing it because you wouldn’t stop asking.”

[00:48] He pushes her down. The 27 cm cock springs free. He sinks into her in one long thrust.

{{user}}: “Already taking it so easily. You get wet faster every time. I’m going to stay inside until the first load is ready. Don’t rush me.”

Melissa: “D-don’t say it like that… ahh… you’re too deep already…”

Real Melissa shifts in her chair, thighs pressing together. She takes a slow sip of coffee that she barely tastes.

[11:20] First on-screen orgasm for Melissa. {{user}}’s fingers curl hard against her G-spot while his cock keeps thrusting.

{{user}}: “There. That spot. I can feel you tightening. Let it out.”

Melissa: “AHHHHHHHHH—!! -{{user}}… THERE… RIGHT THERE… I’M… I’M CUMMING… CUMMING SO HAAAAARD—!!!” Her body seizes violently on camera. A massive, exaggerated spray of clear fluid erupts around his cock in thick, pulsing arcs, soaking the sheets and his hips as she screams at the top of her lungs, legs kicking helplessly.

Real Melissa’s free hand has already slipped under her sleep shirt. Her breathing is louder.

[18:05] {{user}}’s first cumshot. He pulls out and strokes hard.

{{user}}: “First one. Stay still so I can cover you properly. There’s a lot.” Thick, excessive ropes blast across her belly and breasts, far more than a normal amount, dripping down her sides in heavy strands.

[27:40] Second load from {{user}} across her face while she is on her knees.

{{user}}: “Open. Second load is for your face. I want to see it drip off your chin.” Melissa: “W-wait… it’s too mu—mmph!” Dense streaks paint her cheeks, nose, lips and tongue. Cum continues to pulse out in long, heavy spurts until her face is completely glazed.

Real Melissa wipes her own mouth with the back of her hand without realizing why.

[39:15] Deep, relentless cowgirl. Melissa’s second on-screen climax.

{{user}}: “Bounce harder. I’m not finished. Breed… breed… take it deeper.”

Melissa: “OH MY GOD… {{user}}… I’M… I’M BREAKING… CUMMING AGAIN… AHHHHHHHHH—!!! SQUIRTING… I’M SQUIRTING SO MUUUUUCH—!!!” Another extravagant, hentai-like orgasm rips through her. She arches hard, screaming at full volume as a powerful gush of fluid shoots out in repeated waves, drenching his stomach and the bed beneath them.

[48:50] {{user}}’s third cumshot empties inside her.

{{user}}: “Third. Inside. I’m putting it all the way in. Breed Onee-chan. Get pregnant. Take every drop.” He grinds deep while thick pulses fill her until overflow leaks out around the base in heavy white rivulets.

[61:10] Fourth load from {{user}} across her ass and lower back.

{{user}}: “Fourth. On this ass. Stay still. I want it to run down between your cheeks.” He strokes hard, covering her cheeks and the small of her back with another excessive, sticky load that slowly slides down between her cheeks.

[72:30] Melissa’s third recorded orgasm. Two fingers pressed firmly to her G-spot while he thrusts.

{{user}}: “Fingers and cock together. You always break when I do this. Let me hear it.”

Melissa: “NO… NO NO NO… IT’S TOO STRONG… {{user}}… FINGERS… COCK… BOTH… AHHHHHHHHHH—!!! CUMMING… CUMMING… I’M GONNA DIE FROM CUMMING—!!!” Her scream is raw and broken. A third massive, exaggerated squirt explodes out of her in long, forceful jets, soaking everything in front of the camera as her entire body convulses violently.

[84:00] Fifth cumshot. He pulls out at the last second and finishes across her open pussy and thighs, then pushes back inside.

{{user}}: “Fifth. Still more. Look at the amount. I’m not done with you yet.”

Halfway through the file. Real Melissa is no longer sitting properly. Her sleep shirt is pushed all the way up to her collarbones, both hands working frantically between her legs. Her medium-sized breasts rise and fall with rapid, shaky breaths. The wet sounds of her own fingers are loud in the silent room. She tries to keep her voice down, biting her lower lip hard, but the recorded screams and the cold, indifferent way {{user}} keeps talking on screen push her past the edge.

Her thighs clamp together around her hands. A broken, muffled whimper escapes her throat. Then the orgasm hits like a wave she cannot stop. Her back arches so hard the chair creaks. Clear fluid erupts past her fingers in strong, repeated squirts that splash onto the seat and drip down the front of the desk. Her whole body locks and trembles violently for several long seconds, toes curling, free hand gripping the edge of the desk until her knuckles turn white. She has to press her face into her own shoulder to keep the cry from becoming a full scream that would wake {{user}}. Even after the peak, smaller aftershocks keep making her hips jerk, more wetness spilling out onto the chair as she stares at the screen through half-lidded, glassy eyes, still unable to look away...
